- Types of Smooth Muscle. Single-unit (unitary) smooth muscle, called visceral muscle, is the most common type of smooth muscle. It contracts rhythmically as a unit, is electrically coupled by gap junctions, and exhibits spontaneous action potentials.mooth muscle cells are small, spindle-shaped cells with one central nucleus, and lack the coarse connective tissue coverings of skeletal muscle. Smooth muscle cells are usually arranged into sheets of opposing fibers, forming a longitudinal layer and a circular layer.

- The glomeruli of the kidneys contain a smooth muscle like cell called the mesangial cell. Smooth muscle is fundamentally different from skeletal muscle and cardiac muscle in terms of structure and function.  For the source and more detailed information concerning this subject, click on the related links section (Answers.com) indicated below.unction of smooth muscles depends on the tissues where they are present.... In blood vessels, when the smooth muscles contract, they constrict the lumen of the blood vessels … (arteries) thus increasing the blood pressure, and when they relax, the lumen increases in diameter and thus brings down the blood pressure..

Structural Biochemistry/Cell Signaling Pathways/Muscular System SMOOTH MUSCLE - STRUCTURE. Smooth muscle (shown below) is made up of fusiform (diamond-shaped) cells with a single nucleus. The cells are arranged in sheets and contain three filament types: a) actin filaments with no troponin and tropomyosin (5 - 8 times more actin than skeletal muscle).

- Medical Definition of Smooth muscle. Smooth muscle: Along with skeletal and cardiac muscle, one of the types of muscle tissue in the body. Smooth muscle generally forms the supporting tissue of blood vessels and hollow internal organs, such as the stomach, intestine, and bladder. It is considered smooth because it does not have the microscopic lines (the striations) seen in the other two types of muscle.

Difference Between Smooth Muscle and Cardiac Muscle Smooth muscles are of two major types known as single unit, aka unitary, smooth muscles and multi-unit smooth muscles. The single unit smooth muscles contract and relax together, as the nerve impulse excites only one muscle cell, and that is passed on to other cells through gap junctions. In other words, a unitary smooth muscle functions as a single unit of cytoplasm with numerous nuclei.

Carefully pin out to shape, then put iron onto steam, hold about 1-2 inches above project and allow steam to penatrate for approximately 10 seconds at a time, while gently patting with finger tips any irregularities in the knitting to even out. Do this all over project until you have covered it all.

Muscle Spasms 1 Skeletal muscle moves the external body parts, like the arms and legs, neck, back, trunk, and the face. 2  Smooth muscle moves portions of hollow structures inside the body. 3  Examples include the muscles that line the esophagus, stomach, and intestines, muscles that line large arteries, and the muscles of the uterus.

- A: Examples of involuntary muscles, also known as smooth muscles, are the muscles of the urogenital tract, digestive tract, circulatory system and respiratory tract. Involuntary muscles are not controlled by the organism's will. Their actions are automatic and facilitated by the autonomic nervous system.

- This is why skeletal muscle is called STRIATED MUSCLE (i.e., the alternating light and dark areas look like stripes or striations). The light areas are called the I-BANDS and the darker areas the A-BANDS. Near the center of each I-BAND is a thin dark line called the Z-LINE (or Z-membrane in the drawing below).

- Smooth muscles are also found in your bladder. When they're relaxed, they allow you to hold in urine (pee) until you can get to the bathroom. Then they contract so that you can push the urine out. These muscles are also in a woman's uterus, which is where a baby develops. There they help to push the baby out of the mother's body when it's time to be born. You'll find smooth muscles at work behind the scenes in your eyes, too.

- Smooth muscle is called involuntary muscle because you can not control this type of muscle movement. These muscles line internal organs, blood vessels, and organs such found in the digestive and reproductive systems.

Why does smooth muscle have no striations? In a myofibiril you have thick fibers of myosin crossed with thin fiber's of actin. To clarify a myofibril is just a unit of these crossed fibers. In striated muscles, such as cardiac and skeleton, the ration of actin to myosin is something like 5:1 or something similar to that. Smooth muscle however has something around 15:1 ration of actin or mysin fibers. The result of myosin and actin fibers is that they work together to contract the muscle.

- Smooth muscle is found in the walls of hollow organs like your intestines and stomach. They work automatically without you being aware of them. Smooth muscles are involved in many 'housekeeping' functions of the body.

What are Involuntary Muscles? Both smooth muscle and cardiac muscle can be classified as involuntary muscles. Smooth muscle is comprised of spindle-shaped cells that have no striations and is found in numerous locations throughout the human body. Cardiac muscle is striated rather than smooth, and is found only within the walls of the heart.mooth muscles are involuntary muscles composed of thick and thin protein filaments that are homologous to the organelles known as myofibrils found in skeletal muscles. The thin filaments are composed of a globular protein called actin, while the thick ones are made up of a motor protein called myosin.
